How to Manage Pests

Pests in Gardens and Landscapes

Strawberry crown moth—Synanthedon bibionipennis

Larvae are white with a brown head. Adult moths have a black body with two or three bright yellow marks on its thorax and abdomen. Its wings are transparent.

Life cycle

Damage

Larvae feed on the crown and root tissue of plants. Plants wilt and become stunted. Foliage turns red. In strawberries, plants separate from the root at the crown line when pulled.

Solutions

Remove damaged plants or prune out infestations. Clean up any debris underneath plants. Insecticides are usually not effective.
